High Usage Charge

As part of ongoing changes in electric rate reform across California, the California Public Utilities Commission (CPUC) directed SDG&E and the other California investor-owned utilities to implement a High Usage Charge to encourage customers to conserve energy.

The High Usage Charge applies to customers on the Standard residential tiered plan whose energy use is above 400% of their baseline allowance, which is considered well above the typical usage for the average household. Once a customer reaches the High Usage Charge threshold, it triggers a higher price for all electricity used beyond the 400% mark for the remainder of that billing cycle.

For customers who reach the High Usage Charge, it can have a significant impact on their bill. 

Customers can still avoid the High Usage Charge by enrolling in a Time-of-Use plan, which is not subject to the High Usage Charge.

How much is it?


p>Note: As part of a larger rate relief effort across the state, in response to COVID-19, the California Public Utilities Commission (Commission) temporarily reduced the price of high usage electricity by 30%. This lower price is represented below.

Baseline Allowance

The Baseline Allowance is the amount of energy required to cover your basic household needs such as lighting, cooking, heating and refrigeration. Your individual baseline is reviewed and approved by the State of California and is determined by your climate zone, season number of days in your billing cycle and whether you’re a gas-only or gas and electric customer.

How does knowing your baseline allowance help you avoid the High Usage Charge? The purpose of the High Usage Charge is to encourage energy conservation. This state-mandated charge only impacts you if your household exceed 400% of your baseline allowance. This is similar to how the data plan for your mobile phone works, where you're charged more for data use in excess of your allocated data. Knowing your baseline and managing when and how much energy you use may result in lowering your energy bills.
